Backwoods Composites
Poisiflex
A Patent Pending technology that greatly increases the dynamic non-linear geometric stiffness of the bow limb. The limbs are built flat across the width but as the archer flexes back the limbs the cross sectional stiffness increase by going from flat to concave, also known as structural morphing. This is done by advancements made in the limb backings.
Curvanocci
The new shape to recurve bows! The limb shape is mathematically calculated to match the Fibonacci Spiral. The construction gives the limbs almost a never ending smoothness to the draw.
Bow Marrow
A highly advanced limb core material that we manufacture ourselves called "Bow Marrow". It's made from aerospace grade aramid honeycomb core filled with our proprietary high strength low density filler. In comparison to hard maple, it's stronger, lighter and lessens the vibrational effects of the limbs.
Spread Tow
Our limbs are the first to use carbon fiber "spread tow" technology in our very unique carbon weave you see on the outside. By spreading and effectively flatting the carbon fibers bundles in the weave, the fabric behaves more like unidirectional fiber. The fibers are straighter rather than weaving in and out of other bundles. The straighter fiber is therefore stiffer and stronger. This enables us to design a limb with much less carbon producing a lower density limb. Lower density greatly enhances the limbs efficiency.
Shear Center
Shear center is a point on a beam-section where application of loads does not cause twisting. We designed our risers to have a shear center directly in line with the load path between the upper and lower limb, thus creating a riser with zero torque.
Math Mathematical Modeling/Simulation of Recurve Limb Design
Using Finite Element Method (FEM) of simulating a multiple designs we were able to optimize our three limb designs for performance and durability in each of their design purpose
High Density Composite ILF Limb Wedge
Our high density composite ILF wedge material was in house designed and fabricated. It provides a tougher wedge for high poundage limbs, high mass for increase in mass moment of inertia for greater bow resistant to movement and dampens vibrations.
"Stealth Coat"
We give all our bows what we like to call "Stealth Coat". It is a low observable type coating which consists of a under coat of epoxy and outer coating of high matte textured urethane, perfect for situations where you want low visibility
